'I Claims. l

This invention relates particularly to what are commonly called paper containers.

Paper containers for liquids especially for dispensing milk are in great demand. These quite obviously must be leak proof and sanitary under the severe conditions of transportation anduse. Naturally they must be reasonable in cost of pro- It is also highly desirable that the contents be readily accessible and that when opened the container can be closed and will still be sanitary. It is also desirable that the container provide for free pouring of all the contents, i. e. that there be no vpockets at the discharge outlet.

After several years of research and study of the problem, I have at last discovered the solution. as shown and described herein.

The container comprises a body and a, topA or cover member with a closure member connected or sealed to it in such a way that it is leak proof and yet the closure member can beunsealed and released and opened when desired. The bottom maybe formed in any suitable manner.` The top and the closure member have flanges along twov sides` overlapping two adjoining edges of the body. The fianges of the top member are permanently cemented to theI body of the container and the flanges of the closure are detachably but completely sealed by strips attached to or integral with the body of the container. The other two sides of the top member may have anges permanently cemented to corresponding edges of the body or one side may be integral with the fourth edge of the body.

The accompanying drawings show the preferred form and modifications of my invention.

Fig. 1 is a perspective view of a container embodying one form of my invention, the closure member being shown open.

Fig. 2 is a plan view showing the closure member closed and sealed.

Fig. 3 is an exploded v iew showing a top member and the upper end of the body member and a sealing strip.

Fig. 4 is a fragmentary sectional view showing the way in which the closure is sealed.

Fig. 5 is a plan view and horizontal sectional view taken on a plane through the ange of Ithe cover, the body and the sealing strips.

Figs. 6 and 7 are detail views oftwo separate sealing strips.

Fig. 8 is a plan view of a blank from which a l separate top member or cover with integral edge anges may be formed.

Fig. 9 shows a blank from which a container with a top member and sealing strips integral with the body may be formed. Y

Fig. 10 is a, plan view of a blank from which two integrally connected sealing strips may be formed.

The body Ill of the container may be formedl of fibre or card board or other suitable material and is rectangular in horizontal cross-section. The top or cover member II has a closure member I2 hinged by a scored or weakened line across one corner to close a triangular opening I2 in the corner of the body. The sides I4, I4 mayhave flanges which overlap and are cemented to edges of the body. 'The other sides of the top have flanges I5, I5 which are. cemented to the edges I6, I6 of the body and the flanges Il, I1 of the closure detachably ft outside of the edges I6, I5, when the closureI is in the closed position. Tab

Ila connects I1 and I1.

In order to completely close the joints between the flanges I1, Il and the edges of the body and the joints between the ends of adjacent flanges I5 and I'I, I provide special sealing strips I9 and 20 such as are shown in Figs. 6 and 7. These are frequently formed separately as shown or may be integral with edges of the body as shown at I9' and 20' in Fig. 9, or connected as are I9" and 20" in Fig. 10. Each strip has three parts 2I, 2 I and 2I" and such as 22, 22 and 22" with creased or scored lines separating adjacent parts so that they can be folded to embrace .the flanges I5 and I1 when the container is sealed. The parts 2I and 22 are integral with the edges I6, I6 or may be cemented in place before the top member is applied. By using separately formed sealing strips of suitable' character, I may employ thinner and more readily foldable material than is required for the body and top of the containers. The parts 2l and 22 are folded up around the flanges I5 and I1 and the parts 2|" and 22" are folded over the edges of the top member. These flange 1 parts 2I, 2|", 22' and 22" are detachably held in place for instance by the use of wax or the like when the container is sealed.

For additional security, I may extend the tip of strip 2l) at 23 (Fig. 6) so as to overlie the corner 'of the body and the anges I1, I1, when the parts closure I2, will be permanently connected the body o! the container which will be filled through the opening l2' after which the closure will be closed and the sealing strips folded over and able scoring between the relatively foldable parts such as the body l, the top Il" and the sealing strips I9', 20'. The top has flanges I5", l5",

I4 and the closure l2 has flanges Il", I1" and the tab llc. The method of joining the various flanges and sealing strips will be obvious from the foregoing. A

'I'he top may also be formed by drawing or molding so that the side flanges are integral with the top and closed at corners.

Accordingvto Fig. 10, the two sealing strips I'S and 20" are formed of a single piece to be applied to a body by connecting the edges in the same way that the strips I9 and 2li of Fig. l are applied.

Although there are many paper containers now on the market none of them so far as I can ascertain are entirely satisfactory especially with respect to the requirements of complete freedom from leakage and absolute cleanliness.

Although a is most desirable w su the container through the opening l2 after the top has been cemented to the body, it shall be understo'od that the top and closure may be secured in place and the container filled from the bottom.

According to my invention, the yuse of the sealing stripswith the container having a corner discharge spout makes it possible to obtain complete protection on all counts. 'Theclosure is completely sealed and yet can be opened readily, poured freely and again closed-so as to maintain a thoroughly sanitary condition. Because of the location of the discharge spout in the corner, it is convenient to pour freely or drink from the container and without splashing or requiring the use of a straw.

The movable parts of the sealing strips of course may be torn off when the container has been opened. After the container has been opened and liquid poured from it, it will be seen -that the lip of the outlet can be completely covered by closing the corner closure so that itis thus absolutely protected from any possibility of i outside contamination, a highly important hygienic feature.

I claim:

1. A container formed of paper and comprising a body portion of angular cross-sectional shape and a top portion having flanges overlapping at least two adjacent side edges of the body, said ton being scored across the corner intervening said side edges to form a closure and said flanges being interrupted at the ends of said scores to facilitate hingng of the corner of the ton along the scored line. and sealing strips secured to the outer edges of the body portion along said adjaing detachably sealed to theouter surfaces of the top portion.
